... constant levels of fat, similar to the way that a thermostat
in a house maintains constant temperature. Previous research by Dr. Cone and other scientists also found that blocking a related neuropeptide receptor, called the MC4-R, in the brains of mice stimulates food intake and ultimately causes obesity. ...
